SHEET-DELIVERING APPARATUS FOR PRlNTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No.311A32, dated January27, 1885.

Application filed July 7, 1982.

To all whom it may concern.-

Be it known that I, BER'rHoLD HUBER, of Taunton, in the county ofBristol and State of Massachusetts, have invented a certain new anduseful Improvement in Sheet-Delivery Apparatus for Printing-Presses, ofwhich the following is a specification.

. My invention is applicable to cylinder printing-presses, and relatesto the arrangement of the fly for taking the sheets from the tapes anddepositing them upon the fly-board.

The invention consists in the con'ibination. with a fly having ahorizontal shaft, which is i'ulcrumed at one side of the press or nearone end of the shaft, so that it may be swung in a horizontal plane froma position crosswise of the press toward a position lengthwise of thepress, of devices for giving such swinging movement of the fly-shaft andat the same time turning the shaft so as to reverse the fly-fingers anddeposit the sheet.

The invention also consists in novel details of construction andcombinations of parts in the mechanism for imparting thebefore-described double movement to the fly-shaft.

In the accompanying drawings, Figure 1 represents a verticallongitudinal section of a part of a press embodying my improvement. Fig.2 represents a plan thereof, the side frames only beingin horizontalsection. Fig. 3 represents an end elevation, and Fig. trepresents adetail view on a larger scale of one of the receiving-wheels and tapewheels or rollers.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the foundation-plate of the press, and A designates theside frames supported thereon.

B designates the impression-cylinder mounted in hearings in the sideframes, A. The cylinder is provided with ordinary grippers, a, fortaking the sheets from the feed-board O, the grippers being operated inany ordinary way. Below the feed-board is arranged a shaft, D, which maybe operated by a handcrank, D, or other suitable means, and the shaft Dcarries a spur-wheel, D which engages with a wheel, B, of double itssize upon the cylinder'shaft, and thereby imparts motion to thecylinder.

Upon the shaft D are a number of receiving.-

(N'o model.)

wheels, D and through these wheels extends a gripper-shaft, I), providedwith a gripper, c, for each wheel, which is received in a recess, c, inthe side of the wheel, as shown in Fig. 4. The grippers c are secureddirectly ,upon and are supported by the gripper-shaft in g-wheels DAround the small rollers or wheels e are passed tapes or bandsf,t11eupper sides of which are tangential to the receiving-wheels D and thesetapes also pass around larger rollers or wheels 9 upon a shaft, as bestshown in Figs. 1 and 2. The shaft 9 is rotated positively-as here shown,from the shaft D-by means of a belt, 9 passing around a pulley, upon theshaft D, and a pulley, g", on the shaft 9. The relative sizes of thepulleys g 9* and the rollers or wheels 6 g should be so proportionedthat the tapes will travel at ex- 4 act] y the same speed as theperipherical velocity of the receiving-wheels D so that thefreshly-printed sheet will not be smutted by the tapes or hands, as willbe the case if said tapes do not travel at the same speed as the sheetis delivered from the wheels D E designates the horizontal fly-shaft,and h the fly-fingers.

F designates a vertical shaft at the side of the press and opposite theend of the fly shaft. The shaft F is madein two parts, as shown indotted lines in Fig. 3, and these two parts are connected by across-head, F. The fly-shaft E passes horizontally through thiscross-head and between the ends of the two parts of the shaft F, andthus the two shafts are connected together, so that the shaft F forms afulcrum on which the shaft E turns.

G designates the fly-board, which is not placed directly in front of thepress, but at one side and in advance thereof. The shaft F is adapted toturn in bearings i, and by so turning it the fly-shaft E is swungoutward in an arc-shaped path, and is brought to the position shown inthe dotted lines in Fig. 2.

Upon the shaft E is a bevel-wheel, j, or a segment of a wheel, and thisengages with a stationary gear-segment,j, secured on the bed A.Consequently it will be understood that as the shaft E is swung bodilyoutward it is also turned by the gear-segment j turning on thestationary segment j, and reverses the fly to deposit the printed sheeton the fly-board G. By a reverse movement of the shaft F the fly-shaftis swung back into its former'posi-' tion, and is turned so as to bringthe fingers into posit-ion to receive the sheet.

Any suitable mechanism may be employed to give the shaft F the desiredrotation alternately in opposite directions. In this exam- 1e of myinvention I provide a cam, H, upon the shaft of the cylinder B, and ahorizontallymoving bar, I, having a roller, is, at one end entering thegroove in the cam, and a rack, l, at the other end engaging with asegment-gear, m, on the shaft F. The bar I is slotted or bi,-

fu rcated to receive the cylinder-shaft through it, and asthe bar isreciprocated bythe cam H the shaft F will be turned alternately inreverse directions.

In the operation ofmy press the sheet is taken by the grippers of theimpression-cylinder and is carried downward to receive the impressionfrom the form on the bed. When the head of the sheet reaches thereceivingwheels D their grippers, which have previously been opened, areclosed on the head of the sheet, and by them the sheet is transferredonto the receiving-wheels. As the head of the sheet reaches the tapesthe grippers of the wheels D are opened and the sheet moves downwardonto the fly, and when nearly the whole sheet is on the fly thefly-shaft is swung outward and turned to deposit the sheet onto thefly-board G.

What I claim as my invention, and desire to secure by Letters Patent,isv

' 1. In a printing-press, the combination,with a fly having a shaftfulcrumed at one side of the press, of devices,substantial1y asdescribed, for imparting a swinging motion to said flyshaft upon itsfulcrum, and for instantaneously rotating it to reverse the fly anddeposit the sheet, substantially as specified.

2. In a printing-press, the combination,with

a fly-shaft and an upright shaft to which the fly-shaft is connected, sothat the upright shaft forms a fulcrum for the fly-shaft, of devices,substantially such as described, for imparting a rotary motionalternately in opposite directions to the upright shaft, a gear upon theflyshaft, and a stationary gear engaging therewith and servingto turnthe fly-sh aft, substantially as specified.

3. The combination of the fly'shaft E, the

upright shaft F, the gear j, the stationary gear j, the cam H, therack-bar I, and the gear m on the shaftF, substantially as specified.
